The first inner cavity 110 and the second inner cavity 120 which are communicated with each other are closed, namely, the pressure bag 96 is formed, and the fluid pressure sensor 97 is arranged in the first inner cavity 110, so that the fluid pressure sensor 97 can detect the pressure in the pressure bag 96. The flexible sleeve 121 may be made of a biocompatible material, such as silicone, which is flexible to clean and re-disinfect, is dedicated to a person, fundamentally solves the risk of infection, and reduces the economic burden on the patient.
Alternatively, the fluid comprises a gas or a liquid, such as a biosafety compatible plant essential oil or the like. It will be appreciated that the fluid pressure sensor 97 is adapted to different fluids, e.g. the fluid is a gas, and the fluid pressure sensor 97 is accordingly a gas pressure sensor; if the fluid is a liquid, the fluid pressure sensor 97 is correspondingly a liquid pressure sensor.

The basin bottom detecting apparatus of the third embodiment of the present invention is substantially the same as that of the first embodiment, and the description thereof will be omitted for the same parts, and only the differences will be described below.
Referring to fig. 10 to 13, fig. 10 is a schematic diagram of a switch assembly according to a third embodiment of the invention;
fig. 11 is a schematic diagram of the switching on and shutting down implementation principle of the hall sensor according to the third embodiment of the present invention; FIG. 12 is a power-on/off flow chart of a basin bottom detection apparatus according to a third embodiment of the present invention; fig. 13 is a schematic diagram of the switching on and shutting down implementation principle of the reed switch according to the third embodiment of the present invention.
The basin bottom detection apparatus provided in the third embodiment includes a main body portion 10, a non-direct contact type switch assembly 20, a switch control circuit 92, and a pressure detection assembly; the pressure detection assembly is arranged on the main body part 10, a part of the main body part 10 is used for being inserted into a preset object body, and the pressure detection assembly is used for detecting the contact pressure between the main body part 10 and the preset object body; the switch assembly 20 is configured to send a control signal to the switch control circuit 92 under non-direct contact operation, the switch control circuit 92 controlling the pressure detection assembly to be turned on or off according to preset logic when the received control signal satisfies a preset condition.
The inventor finds that for common wearable equipment, the traditional on-off scheme generally adopts a mechanical key, however, as the basin bottom detection equipment needs to enter a human body to collect data, the mechanical key is not easy to operate and is not easy to sterilize and waterproof. Thus, the switch assembly 20 provided in this embodiment is not in direct contact, and the switch assembly 20 can output a control signal under the operation of not in direct contact. The non-direct contact switch assembly 20 is simple in structure and easy to clean, and avoids the problem that mechanical keys are not easy to sterilize and waterproof. However, since the control signal output by the switch assembly 20 is not as stable as a normal mechanical key switch due to the non-direct contact operation, the switch control circuit 92 needs to be reasonably configured, so that the switch control circuit 92 can control the pressure detection assembly to be turned on or off according to the preset logic when the control signal meets the preset condition, thereby avoiding false triggering.
Referring to fig. 10, in an alternative embodiment, the switch assembly 20 includes a magnetic sensor 21 and a magnetic member 22 adapted to the magnetic sensor 21; the non-direct contact operation includes the relative position of the magnetic member 22 and the magnetic sensor 21 being close to each other, until the magnetic sensor 21 is triggered by the magnetic field of the magnetic member 22. Optionally, the magnetic sensor 21 includes a hall sensor or a reed switch. Both hall sensors and reed switches are common magnetic sensors that can be triggered by the magnetic field of a magnetic member 22 (e.g., a magnet). Preferably, a magnetic sensor 21 is provided as a sensor part of the switch assembly 20 in the head 11. So configured, the magnetic sensor 21 can be closely coupled to the switch control circuit 92 disposed in the first cavity 110 of the head 11, reducing transmission interference between the two and reducing the cost of the arrangement.
Optionally, the magnetic sensor 21 is configured to be in a high resistance state when not triggered by the magnetic field of the magnetic member 22; when triggered by the magnetic field of the magnetic member 22, is in a low resistance state. A hall sensor, which may be a switched hall sensor, having only two states of high resistance and low resistance, will be described below as an example of the magnetic sensor 21. In a normal state (i.e., the hall sensor is not subjected to the magnetic field from the magnetic member 22), the hall sensor is in a high-resistance state, and when the magnetic member 22 approaches and the magnetic flux is greater than the set value, the hall sensor is triggered to be in a low-resistance state. Further, the switch control circuit 92 controls the pressure detecting assembly to be turned on or off according to the output of the hall sensor.
Referring to fig. 11, which shows an example of a principle of implementing a switch on/off of the magnetic sensor 21 using a hall sensor, the switch control circuit 92 includes a conduction switching unit 921, a self-locking unit 922, and a control unit (e.g., a main chip that may be a basin bottom detection device);
the input end (i.e., pin 2 of U2 in fig. 11) of the on-switching unit 921 is used for connecting to a power source (i.e., the positive output end of the battery circuit 91), the output end (i.e., pin 4 of U2 in fig. 11) of the on-switching unit 921, VBATOUT, is respectively connected to the control unit and the pressure detecting component, and the control end (i.e., pin 3 of U2 in fig. 11) of the on-switching unit 921 is connected to the output end (i.e., pin 2 of the hall sensor U1 in fig. 11) of the switching component 20; in an alternative embodiment, the control unit and the pressure detection assembly may be integrated in the same main chip, which is led out with the unused pins of the main chip, respectively. Of course, in other embodiments, the control unit and the pressure detecting component may be separately provided, which is not limited in this embodiment.
The input end (i.e., 6 pin of U2 in fig. 11) of the self-locking unit 922 is connected to the output end of the switch assembly 20, the output end (i.e., 5 pin of U2 in fig. 11) of the self-locking unit 922 is grounded, the control end (i.e., 1 pin of U2 in fig. 11) of the self-locking unit 922 is connected to the first end (i.e., DIO12 in fig. 11) of the control unit, and the second end (i.e., DIO0 in fig. 11) of the control unit is connected to the output end of the switch assembly 20;
the preset logic includes:
when the on-switching unit 921 is in an off state, the on-switching unit 921 is turned on after receiving a control signal from the switching unit 20, the control unit sends a first signal to a control end of the self-locking unit 922 through a first end DIO12 thereof, so as to drive the self-locking unit 922 to be turned on, so that the on-switching unit 921 is self-locked in an on state, and the pressure detecting unit is turned on;
when the on-switching unit 921 is in an on state, after receiving a control signal from the switch assembly 20, the second end DIO0 of the control unit sends a second signal to the control end of the self-locking unit 922 through the first end DIO12 of the control unit, so that the self-locking unit 922 is driven to be disconnected, the on-switching unit 921 is released from self-locking, the on-switching unit 921 is disconnected, and the pressure detection assembly is closed.
Before use, the basin bottom detection device can be started and shut down in vitro to complete a certain test, and then enters a human body. In the switch assembly 20 that is not in direct contact, the magnetic element 22 only triggers the magnetic sensor 21, but rather than the magnetic sensor 21 being kept outputting as in a common mechanical switch, the magnetic element 22 is generally removed after the magnetic element 22 triggers the magnetic sensor 21, so the switch control circuit 92 needs the self-locking unit 922 to lock on or off the on/off of the on/off switching unit 921, so that the switch control circuit 92 can reliably and stably operate.
In an alternative embodiment, the conduction switching unit 921 includes a PMOS transistor, a source S2 of the PMOS transistor is configured as an input terminal of the conduction switching unit 921, a drain D2 of the PMOS transistor is configured as an output terminal of the conduction switching unit 921, and a gate G2 of the PMOS transistor is configured as a control terminal of the conduction switching unit 921; further, the gate G2 of the PMOS transistor is connected to the output terminal of the switch assembly 20 through the first resistor R3 and the diode D2. It can be understood that when the magnetic member 22 approaches the hall sensor U1 and the magnetic flux is greater than the set value, the hall sensor U1 is in a low-resistance state (i.e. corresponding to the switch assembly 20 sending a low-level control signal), and the gate G2 of the PMOS transistor is pulled down through the first resistor R3 and the diode D2, so that the PMOS transistor is turned on, and the control unit and the pressure detecting assembly are powered on. In other embodiments, the on-switch 921 may include a PNP transistor instead of a PMOS transistor, and those skilled in the art may replace other surrounding elements according to the prior art.
The self-locking unit 922 includes an NMOS transistor, a drain D1 of the NMOS transistor is configured as an input terminal of the self-locking unit 922, a source S1 of the NMOS transistor is configured as an output terminal of the self-locking unit 922, and a gate G1 of the NMOS transistor is configured as a control terminal of the self-locking unit 922. After the control unit is powered on, the level of the first end DIO12 (for example, the level may be a control IO of the main chip) may be configured to be in a pulled-up state according to a preset program or logic, so that the NMOS transistor is in a conducting state, at this time, the drain D1 of the NMOS transistor is in a low level, the gate G2 of the PMOS transistor of the conducting switching unit 921 is in a low level through the first resistor R3, at this time, even if the magnetic element 22 is removed, the hall sensor U1 is converted into a high-resistance state, and due to the existence of the diode D2, the low level state of the gate G2 of the PMOS transistor is not affected, that is, the conduction of the PMOS transistor is maintained, and the power supply to the control unit and the pressure detecting component is maintained. The static power consumption of the switch control circuit 92 adopting the PMOS tube and the NMOS tube can be controlled below 10 mu A, the power consumption is low, and the reliability is high. It is appreciated that in other embodiments, the self-locking unit 922 may include an NPN triode instead of an NMOS tube, and those skilled in the art may replace other surrounding elements according to the prior art.
Further, the second terminal DIO0 of the control unit is configured as a shutdown detection terminal, which is connected to the output terminal of the switch assembly 20 (i.e. the 2 pin of the hall sensor U1 in fig. 11) through the diode D1, and is also connected to the reference power Vref through the resistor R1. The second end DIO0 starts to work after the control unit is powered on, when the hall sensor U1 is in a high-resistance state without being influenced by the magnetic piece 22, the second end DIO0 is pulled up by the reference power Vref, and at this time, the control unit determines that the pressure detection assembly is in a normal working state according to a preset program or logic.
When the user is ready to turn off, the magnetic piece 22 is used to be close to the Hall sensor U1 again, the Hall sensor U1 is converted into a low-resistance state by the magnetic field of the magnetic piece 22, the second end DIO0 is pulled down through the diode D1, the control unit can detect a low-level signal of the second end DIO0, when the low-level signal of the second end DIO0 meets the preset condition, the level of the first end DIO12 is controlled to be configured to be low, the NMOS tube is cut off, the drain D2 of the PMOS tube is not output, and the control unit and the pressure detection assembly are closed.
Optionally, the source electrode S2 of the PMOS transistor is connected to the gate electrode G2 of the PMOS transistor through the second resistor R4 and the first capacitor C4. When the user is ready to shut down, after the low level signal of the second end DIO0 meets the preset condition, the first end DIO12 is low level, the NMOS tube is cut off, and at the moment, the grid G2 of the PMOS tube can be pulled high by VBATIN through the arrangement of the second resistor R4 and the first capacitor C4 to cut off the PMOS tube, so that shutdown is ensured. The first capacitor C4 plays a role in time delay, so that the PMOS tube is cut off later than the NMOS tube, and the problem that shutdown cannot be performed is avoided.
For specific level jump manners at the first end and the second end of the control unit, please refer to the following table 1:
TABLE 1
Further, the preset conditions include: the control signals comprise n continuous pulse signals, and the interval between two adjacent pulse signals does not exceed a preset threshold value; wherein n is a natural number of not less than 2. In order to prevent the power on/off from being triggered by mistake, the control unit may further determine whether the control signal meets a preset condition, and when the control signal meets the preset condition, the control unit may control the level of the first terminal DIO12 to perform conversion.
Referring to fig. 12, an on/off flow of the basin bottom detecting apparatus is exemplarily shown. In this exemplary embodiment, when the magnetic member 22 approaches the hall sensor, the control unit receives the control signal from the output of the hall sensor, and at this time, the control unit does not directly control the on/off state, but starts a false triggering procedure, and the false triggering procedure sets the preset condition to the control signal to include 2 continuous pulse signals, and the two level transition time of the 2 pulse signals can be set to 10S. So configured, by detecting whether the two-level transition time of the control signal is greater than 10S, it is possible to determine whether the preset condition is satisfied.
Fig. 13 shows an example of a principle of an on-off implementation of a reed switch as the magnetic sensor 21, where the reed switch U1 in fig. 13 has two connection ends, and the reed switch is a conventional magnetic control sensor, which generally includes a sealed glass tube and two reed sheets disposed in the glass tube, the reed sheets function as a magnetic flux conductor, and the two reed sheets are not in contact when not yet operated; when the magnetic piece 22 approaches to the reed and is influenced by a magnetic field, the externally applied magnetic field causes the two leaf springs to generate different polarities near the end points, and when the magnetic force exceeds the elasticity of the reed, the two leaf springs can attract and conduct a circuit; when the magnetic field is reduced or eliminated, the reed is released due to its elasticity, and the contact surface is separated to be disconnected. The two reeds are respectively led out to form two connecting ends of the reed switch U1. The switch control circuit 92 may refer to the switch control circuit 92 of the hall sensor described above, and will not be repeated here.
[ example IV ]
The basin bottom detecting apparatus of the fourth embodiment of the present invention is substantially the same as that of the third embodiment, and the description of the same portions will be omitted, and only the differences will be described below.
Referring to fig. 14 to 15, fig. 14 is a schematic view of a basin bottom detecting apparatus according to a fourth embodiment of the present invention; fig. 15 is a schematic view of a vibration sensor according to a fourth embodiment of the present invention.
The specific structure of the switch assembly of the fourth embodiment is different from that of the third embodiment. Specifically, as shown in fig. 14, the switch assembly 20 includes a vibration sensor 23; the non-direct contact operation includes the vibration sensor 23 being triggered by vibration. Preferably, the vibration sensor 23 is provided as a sensor portion of the switch assembly 20 in the head 11. So configured, the vibration sensor 23 can be closely connected to the switch control circuit 92 disposed in the first cavity 110 of the head 11, reducing the transmission interference of the two and also reducing the cost of the arrangement. By adopting the vibration sensor 23, the basin bottom detection device can only comprise one component, so that the problem that the additionally arranged magnetic piece 22 is easy to lose in use due to the fact that the additionally arranged magnetic piece 22 is additionally arranged when the magnetic sensor 21 is adopted is avoided. When the device is used, the device can be started and shut down only by vibrating the basin bottom detection equipment, and the device is more convenient to use.
Referring to fig. 15, an embodiment of a vibration sensor 23 is exemplarily shown, which includes an insulating substrate 230, a conductive post 231, and a spring 232, wherein the conductive post 231 is fixedly disposed on the substrate 230, the spring 232 is disposed around the conductive post 231, one end of the spring 232 is fixedly disposed on the substrate 230, and the other end is a free end. When the vibration sensor 23 is stationary, the spring 232 is not in contact with the conductive post 231, and the vibration sensor 23 is in an open state. When the vibration sensor 23 is rocked and reaches the corresponding vibration force, the free end of the spring 232 swings to contact the conductive post 231, and the vibration sensor 23 is in an instant conduction state, i.e. triggered. When the shake disappears, the vibration sensor 23 is restored to the open state.
The switching control circuit 92 adapted to the vibration sensor 23 can be referred to the switching control circuit 92 of the hall sensor described above, and the principle thereof is similar and will not be repeated here.
In particular, since the control signal output from the vibration sensor 23 is mainly a momentary pulse, the control signal cannot be sustained, and the vibration sensor 23 is more likely to be erroneously triggered in practice, as compared with the magnetic sensor 21. The magnetic sensor 21 also requires the approach of the magnetic member 22 to trigger, and the vibration sensor 23 may be triggered by mistake during the process of lifting, moving or lowering the basin bottom detecting device. The control unit is therefore more required to set certain preset conditions of the control signal. The preset condition may be set, for example, such that the control signal comprises three consecutive pulses over a certain period of time. In use, a user can shake the basin bottom detection device for three times with force according to fixed frequency to control the opening or closing of the basin bottom detection device. Of course, those skilled in the art can reasonably set the preset conditions according to the actual situation.
In summary, the basin bottom detection apparatus provided by the present invention includes: the device comprises a main body part, a switch assembly and a pressure detection assembly, wherein the pressure detection assembly is arranged on the main body part; the switch assembly is used for controlling the pressure detection assembly to be turned on or turned off; the main body part comprises a head part and a handle part which are sequentially connected along the axial direction, the head part is used for being inserted into a preset object body, the handle part is used for being partially inserted into the preset object body, the handle part partially extends out of the preset object, and the pressure detection assembly is used for detecting the contact pressure of the main body part and the preset object. So configured, the pressure detection assembly can collect the sphincter contracting pressure in real time after the main body part is inserted into the preset part, so that an accurate and quantitative personalized rehabilitation treatment scheme can be formulated for quantitative monitoring, and the accurate implementation of the treatment scheme is ensured.
It should be noted that the above embodiments are not limited to the embodiments alone, but may be combined with each other, and the present invention is not limited thereto. The above description is only illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, and any alterations and modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the appended claims.
